Your ethos is that of a gamer not a professional developers in that developers want to see some financial reward - not a reward in a game free of capitalism. If it’s a passion project, you need to demonstrate passion i.e something you have done in the WIP section of the forums. Without a reward strategy for developers you wish to “use” and any indication you have used UE4 for more than a week - It encourages feasibility discourse discussions that plague these job offering forums.
Of course this is a red flag as it implies not only programming Multiplayer but Massive which have upkeep costs of running servers - this coupled with your anti-capitalism ideology simply don’t work. I know as I’ve donated many hundreds of dollars to keep servers running for a free game.
Working with computers full time and coming home to work on computers in your spare time will not last - trust me on that
